Optical device having prism-shaped reflector directing opposing light paths onto an image sensor

摘要

A camera can include a housing, two lenses, a prism-shaped reflector, a reflector support surface, and an optical sensor. The two lenses are coupled to the housing in substantially opposing directions. The prism-shaped reflector has two parallel surfaces and three additional surfaces comprising: a first and a second reflective surfaces and a support plane. The reflector support surface is bonded to the prism-shaped reflector at the support plane. The optical sensor includes a surface upon which two non-overlapping image circles are concurrently projected; one from each of the two lenses. Each image circle results from a light path from a respective one of the two lenses being reflected off one of the first and second reflective surfaces onto the surface of the optical sensor.

1. An optical device comprising:
a housing; two lenses coupled to the housing in substantially opposing directions; a triangular prism-shaped reflector having two parallel surfaces and three additional surfaces comprising: a first and a second reflective surfaces and a support plane; a reflector support surface bonded to the triangular prism-shaped reflector at the support plane; a support gap comprising a volumetric support void between the triangle shaped prism and interior components excluding the ninety five percent or more support for maintaining a relative position of the triangular prism-shaped reflector to other components of the optical device results from the reflector support surface being bonded to the triangular prism-shaped reflector support surface as well as an interior surface of the housing, wherein; and one or more optical sensors upon which two non-overlapping image circles are concurrently projected, one from each of the two lenses, wherein each image circle results from a light path from a respective one of the two lenses being reflected off one of the first and second reflective surfaces onto a surface of the one or more optical sensors.
